secure method

Future<SecureSocket> secure (Socket socket, { dynamic host, SecurityContext context, bool onBadCertificate(X509Certificate certificate) })

Takes an already connected socket and starts client side TLS handshake to make the communication secure. When the returned future completes the SecureSocket has completed the TLS handshake. Using this function requires that the other end of the connection is prepared for TLS handshake.

If the socket already has a subscription, this subscription will no longer receive and events. In most cases calling pause on this subscription before starting TLS handshake is the right thing to do.

The given socket is closed and may not be used anymore.

If the host argument is passed it will be used as the host name for the TLS handshake. If host is not passed the host name from the socket will be used. The host can be either a String or an InternetAddress.

Calling this function will not cause a DNS host lookup. If the host passed is a String the InternetAddress for the resulting SecureSocket will have the passed in host as its host value and the internet address of the already connected socket as its address value.

See connect for more information on the arguments.

Implementation

static Future<SecureSocket> secure(Socket socket,
    {host,
    SecurityContext context,
    bool onBadCertificate(X509Certificate certificate)}) {
  return ((socket as dynamic /*_Socket*/)._detachRaw() as Future)
      .then<RawSecureSocket>((detachedRaw) {
    return RawSecureSocket.secure(detachedRaw[0] as RawSocket,
        subscription: detachedRaw[1] as StreamSubscription<RawSocketEvent>,
        host: host,
        context: context,
        onBadCertificate: onBadCertificate);
  }).then<SecureSocket>((raw) => new SecureSocket._(raw));
}
